Abstract
In accordance with a first aspect of the present disclosure, an ultra-wideband communication node is provided, comprising: an ultra-wideband communication unit configured to transmit one or more messages to a plurality of external responder nodes and to receive one or more responses from said responder nodes; a processing unit configured to use a common cryptographic session key to encrypt said messages, wherein said common cryptographic session key is a key shared between the ultra-wideband communication node and all the external responder nodes; wherein the processing unit is further configured to use responder-specific cryptographic session keys to decrypt the responses and/or to encrypt further messages to the responder nodes, and wherein each individual one of said responder-specific cryptographic session keys is a key shared between the ultra-wideband communication node and one of the external responder nodes.
